test: increase clock tick time to fix local failure

[vursen]

Description

Increased the fake clock tick time from 150ms to 200ms to fix the test failure, which apparently happens only locally:

➜  web-components git:(main) ✗ yarn test --group field-base
yarn run v1.22.19
$ web-test-runner --group field-base

packages/field-base/test/field-mixin.test.js:

 ❌ FieldMixin + Polymer > error message > announcements > should not announce error message when field is valid
      AssertionError: expected 'This field is required' to equal ''
      + expected - actual

      -This field is required
